Universal Gravitation Part 2

Today we used your graphs from yesterday to come up with the relationships between the masses, distance between the mass centers, and the magnitude of the gravitational force between the masses.



And there weren't many good problems in the textbook, so I wrote some and put them on a little strip of paper: Universal Gravitation Homework. This is suggested homework, which will be assessed Friday.

After all of this, we attempted a demonstration about the idea that gravity isn't really a force, exactly, but the consequences of bending space-time with large masses. This will not be assessed but it is the currently accepted model.

We also talked about gravitational waves, which are super exciting and the first detection of which was only a few years ago. Here is a pretty awesome video from Science Bulletin: Gravity-Making Waves. This was made before the first detection, though.
